why are you comparing a diesel powered car ( n4) with hybrid car ( moto x) ? even if you did now both are fast, smooth and work great for everything asked to do so .... cores dont really matter

They do not have the same processor. They do not have the same cores either.
Simply put the nexus 4 has krait 200 cores. The moto x has krait 300 cores.
The krait 300 cores are faster clock for clock than the 200. They also of course have a clockspeed advantage too.
All of Qualcomms crazy naming scheme aside. The moto x has basically a dual core S600 at 1.7ghz. Think HTC one m7 with two cores. And those two cores run at the their max frequency quite a bit often to boot....
User psx on nexus 4 and compare them
Sent from my LG-E975 using XDA Premium 4 mobile app
Quick summary:
N4: APQ8064 Krait 200 quad core @1.5ghz
MX: MSM8960DT Krait 300 dual core @1.7ghz
2013 N7: APQ8064AA Krait 300 quad core @1.5ghz
S4: APQ8064AC Krait 300 quad core @1.9ghz
S5: MSM8974ACv3 Krait 400 quad core @2.45ghz
(the fact some are S4Pros and some are S600's means very little, it's mostly K200 vs K300)
The moto x / 2013 N7 / S4 are pretty closely matched perf wise, which makes sense as they're all the same platform.
If you jump two steps between S4Pro -> S600 -> S800 -> S801 then there's a fair sized perf change, much less so with a single step jump.
At stock clocks I dont feel my S4 or 2013 N7 are dramatically faster then my N4.
It's merely that the N4 has the shortest battery life of the 3 (both relative and obviously absolute)
If you OC your N4, you could easily catch up in raw cpu power (if you ignore the fact that you could OC the other device too).
I wouldnt be too surprised if a K200 @~2.0-2.2+ ghz would equal a K300 @1.7-1.9ghz, though you'd shorten battery life even more on a already short life device.
If you could magically OC a N4 to ~3ghz, I wouldnt be surprised if it could keep up with the S5, I also wouldnt be surprised if it dies in 5 mins.
The N4 is very disadvantaged when it comes to thermal throttling, since once it hits the heat ceiling it drops like 20% in performance so it doesnt overheat.
You could also do the heatsink hardmod if it was really important, it's a rather easy mod (if you dont mind the fact you need to take it apart to do)
All devices have a thermal ceiling, but the N4 is usually disadvantaged when it comes to that. It's far easier to hit it on a N4 then any other device.
You could also do the qcom dalvik+bionic mod, it improved benchmark scores on my N7 by 15% (but much less on my N4, also I said benchmark and not "performance", it's very hard to quantify general performance/smoothness)
I think there was a F2FS mod for the n4, if there is and it works you could dramatically improve storage speed if you use that.
Finally you could always throw random build.prop mods, placebo effects are always the best as far as cost/performance goes.

Moto has generally simply been spinning for marketing.
The fact of the matter is that the MSM8960DT is basically varient of the APQ8064AB/Ax that has 2 cores instead of 4.
Devices newer then the MX also have similar coprocessors now to offload idle sensor work, it's a general part of the S800/801 platform.
There's nothing stopping a manu from including them with any equivilent quad core soc,
which is essentially what qcom did with their own coprocessors in the S800/801 platforms.
Battery life on it is about equal to it's APQ8064Ax cousins since they're obviously the same cpu.
Depending on the rom/kernel, you can turn 2 cores off on the N7/S4/whatver,
but you cant turn 2 more cores on the MX.
The moto x has a slightly faster cores and clock speed but as there are too less cores it is slower. The reason it seems faster is the software optimizations Motorola have included on the moto x. Things such as optimized dalvik and bionic and using F2FS. If you install these on the nexus 4 i think it will be quicker.

The nexus 4 is just not quicker no matter what you do.
Quad vs dual is irrelevant. There aren't hardly any workloads on mobile that even require four cores let alone max them out. And if you do its going to throttle very quick anyways.
Krait 300 cores are faster period. The moto x is faster period. The hardware is just faster.
http://www.anandtech.com/show/6747/htc-one-review/11
No software optimization or trickery. Krait 300 is just faster. It doesn't seem faster. It's faster.
Krait 200 was already a old core relatively speaking when the s4 pro came out. It is the same core as the last gen SoC in the s3 class devices. Just with a newer gpu basically.
Can't believe people are still having this silly discussion.

Yes krait 300 is faster than 200, around 20-30%. The fact the nexus 4 does have 2 more cores does make it faster and just because "There aren't hardly any workloads on mobile that even require four cores let alone max them out" doesn't mean the moto x is faster ( at least by my definition of the word). The nexus 4 already beats in benchmarks but if the moto x does beat the nexus in things such as UI its because of all Motorola's software optimizations like i mentioned before.

In the majority of benchmarks that moto X wins. It even beats the quad core s600 devices in many of them as well. Even giving up 50mhz on the gpu to them.
Throttling is a big deal. Those chips throttle quicker and their clockspeeds go way down. The moto X spends more time at the highest clocks.
http://www.anandtech.com/show/7235/moto-x-review/7
Overall no matter how you try and slice it. In the majority of use cases, real world and benchmarks. The moto X is faster
And it doesn't beat it in stuff like ui because of some optimization. It beats it because it is a significantly faster clock for clock and has a clockspeed advantage. And browsing around the ui doesn't use for cores on top of it all. You can easily show that on your nexus 4 with a custom kernel and setting it to dual core only.
It's faster because the platform is faster.

What benchmarks are these? I know the motox has great GPU performance (mostly as it's one of the few snap 600 with a 720p screen) but in CPU performance it usually is lower than quad core s600 devices. For example in geekbench. But yes the moto x is faster than many in real world performance but this is largely due to all Moto's software optimizations.

The article tells you what is used in it. Also for the gpu test many of them have offscreen testing as well which negates the resolution difference.
Again it's faster in many cases because the hardware is just faster period. Just as taking a HTC one m7 and a custom kernel with 2 cores disabled would be faster in real world performance as well compared to nexus 4.
Real world performance is not some micro level threaded benchmark test.

2GB will help with multitasking while the faster processor will help with gaming and to a degree, faster apps.
If it were an iPhone, then the quad core would be much better because apps will actually make use of the amazing gpu. In android, I doubt there will be an app released in the next year or two that realistically benefits from the quad core's gpu vs the dual core's.
Both the dual and quad core will have all of the software optimizations Samsung has done for web browsing. The 2gb memory is probably overkill at this point, but in theory it means that apps will never close in the background since there will be no need to free up new memory.

Here's my thoughts:
1. Still on the Epic 4G I've never had any real lag.
2. Lack of ram can stall a device, but an excess of ram will not make it faster.
3. Mobile quad-cores are new and untested.
4. Android is not designed for quad-core processors.
5. The dual-core US version should easily match the quad-core international.
6. More ram means more easily multitasking/app-switching.

1. Well the whole android cant handle 4 cores i think is false because its derived from Linux and i know those who use 4,6,8 core processor's and use Linux. so if android isn't im sure its all in code is all.
2. More Ram does mean things will run much faster. For Example: playing gta 4 with 4GB of DDR3 Ram @ 1333MHz plays decent but my pc setup that plays gta 4 with 8Gb of DDR2 Ram @ 1333MHz plays faster and loads faster but GPU does factor those speeds too so, in a sense you cant bottleneck them.
Extra RAM. It's going to be a while before the apps/software catches up with having two more cores. Meanwhile even old stuff can benefit from extra memory. Also see it as more future proof as you won't get the lame ass excuses from Samsung about it not having enough RAM to run whatever the latest release of Android is like we got with ICS and the Epic 4G.

You've misunderstood. Android can use 4 cores, of course. What it can't do is use them effectively in a way that creates any sort of advantage. But just as a mention, being derived from Linux source does not make it a full-fledged Linux OS by far.
And on your second point, again, you're comparing to a full PC operating system. Up until now, apps have been designed for phones with far less than 1GB of ram. It really depends on how you use your phone as to how much ram is needed. If you have a video editor running in the background, while playing pandora, and emulating Mario 64 you'll need more than simply browsing the web. But the processor, bus speeds, operating system, etc. all factor into how effectively more ram can be used. For Example: A 32 bit computer can't even use more than 4GB of ram. More ram does not simply mean 'much' more more speed, there are many other limiting factors. You can throw all the ram you want at a netbook, it will never run GTA4.
Off-Topic Edit: I vote 2GB ram over Quad-Core.
I guess then the only thing that will "improve", not that the int'l lacks of, is on the multitasking??
The few videos I saw, they were really fast but that's of course without all the apps that a normal user install. Like I have 38 apps install on my phone and most of the time I open between 9 to 13 apps everyday. Most of the time I have to close it...I guess more for the habit of doing it and of courses need it when playing games.
I read the answer and I kinda feel its true, maybe android is not yet ready for such hardware just yet, does it feels the hardware manufacture is going too fast compare to the software?

I would take the dual core Krait hands down because it is designed from cortex a15. More instruction per clock is better than stacking cores which a phone doesn't even use. I think the 2 gb of ram has more performance advantage.
They also increased the memory bandwidth with new SOC by adding a new dual channel memory controller which the exynos had all along... They fixed alot of the shortcoming of snapdragon processor with the this gen product

That's because Hummingbirds rape Snapdragons. See the following:
Either way if you want LTE at the moment you are stuck with dual core. So the 2GB of RAM is a nice enhancement. The EVO 1x ended up as two models the 1X which is quad core with no LTE and the 1XL which is dual core with LTE.

Where the hell did the epic4g or the iPhone 4 come into the question? My point was that iPhones actually make use of their gpu's better than android phones do, so the difference between the quad core and the dual core gs3 should be minimal in that regard, at least for a while.

This is wrong.
The Krait is very much designed from the Cortex A9. While it shares similarities with the A15, it is not quite as powerful.
Krait is about 60% of the way between the A9 and A15.

No, where'd you even get that from? Krait is slightly below an A15, Qualcomm derived their design from it. Yes, its not a true A15 core. But its the best right now in production.
Qualcomm has a license to mess around with ARMs designs and make their own CPUs, not just copy and slap an "A4" on them like Apple does.

Interesting how someone "Likes" wrong information.
http://www.anandtech.com/show/4940/qualcomm-new-snapdragon-s4-msm8960-krait-architecture
Designing a processor takes an extremely long amount of time. A15 was just barely released a few months ago. No way Krait was designed from it.
Now, Krait borrows some features from A15, but it's missing some important features as well. Krait does feature an extended instruction pipeline over the A9 (11 vs 9 cycles), but it's nowhere near as long as the A15 (15 cycles). Strictly speaking, lengthening a pipeline is less work than shortening it, hence Krait was not designed from the A15.
It's more likely Krait is an evolution of the Scorpion than anything.
As far as Apple, they have no place in this conversation, but if you must.... while they do have a "processor-only" license with ARM, they do farm out to a company to change some transistor signaling to make it more power efficient (they later bought them).
2 years ago, Apple bought Freescale, the only remaining PowerPC processor design company. (aside: The defense industry was largely concerned, as they rely on PowerPC for their power-efficient but high-speed applications). Anyhow, I wouldn't be surprised if they have an architecture license now so they can design their own ARM processors, Qualcomm-style. The main advantage would be integrating LTE radios like Qualcomm does.
Coincidentally it takes about 2 years to fully design a processor.

Adreno 320 gpu. And you can't really refer to graphic cards as having cores per se, its not correct or accurate in any sense and is oy used as a marketing term. A cpu can have cores because every part of the processor is copied over. You could cut a dual core in half and it would still work. However with graphics cards that's not the case. There are many components to a graphics card, pixel rendering units, texturizers, gddram bus, etc etc too many to name. Generally companies like to clone one aspect of the GPU and call it a dual core, which isn't fair considering many other components of the chip haven't been duplicated. The company that comes closest to actually replicating every aspect of the GPU is imagination technologies (they make the powervrsgx 5 series cards used in the iPhone and iPad, hence their steller graphics performance) and even they don't do it perfectly.
What you really need to know is the performance, which is what it comes down to. Compared to the Mali 400+ GPU in the sgs3/note2 you'll probably get similar if not slightly better results. They're roughly equal, which makes the adreno 320 the most powerful GPU on the market aside from the powervrsgx540mp4 used in the iPad 3. But that's a tablet the most powerful mobile GPUs manafacuted right now by arm is the newest Mali T-series, those things are powerhouses!! There's five t-series graphics cards created, the weakest of the five is the t-604 used in the nexus 10 and even that is the most powerful GPU being mass produced. Here's a page with a list of the more powerful t series.

It depends on how the benchmarks are weighted for single core vs multi-core processes.I believe Antutu heavily tests multi-core processes.
Other benchmarks take a balanced approach such as geekbench. If you look at the link above, the Geekbench total scores of the nexus 10 and htc one are actually really close with a slight favor for the snapdragon 600.
If you look at the single core process subscores, the nexus 10 wins.
If you look at the multi-core process subscores, the snapdragon wins. (makes sense: 2 core processor vs 4 core processor).
Because in the real world, a majority of apps are still designed as single core processes, Geekbench will test and weight single and multicore processes fairly equally in calculating total scores.

The Exynos 5 Dual in your Nexus 10 is a Cortex A15, the most powerful type of ARM chip, which is in only a handful of mobile devices so far. The HTC One, by comparison, has a Krait, a souped-up version of the Cortex A9, the older ARM chip that is in most mobile devices. For raw power, they're probably comparable, even though one is dual-core and the other is quad-core, with the Exynos edging out the Snapdragon in those web browsing benchmarks that freshlysqueezed linked to, while the Adreno in the Snapdragon edges out the Mali in many of the GPU tests.
The big difference is probably battery life, as the Nexus 10 can suck 5-10 W max (though 3-4 W of that is probably the huge display), while the HTC One pulls 4 W max. That's why everybody is going with Snapdragon for the current lineup of phones, the combination of high speed and minimal power can't be beat. Even Samsung, who wanted to put its Exynos 5 Octa, with a quad-core Cortex A15, in the Galaxy S4, has admitted to putting Snapdragon in most of the S4s, though that might be related to fabrication problems they're having with the Octa.
One reason the HTC One might seem "blazing fast" when compared to the Nexus 10 is that the Nexus 10 screen has twice as many pixels as the HTC One's display, though I doubt you'd notice any lag. I don't think the Nexus 10 will have any problems getting updates, as it's the first Android device with Cortex A15 and all high-end Android devices will be getting Cortex A15 over the next couple years. So the Nexus 10 is already ahead of the game.
The one big miss with the Exynos 5 Dual in the Nexus 10 is that it doesn't have a low-power core for light usage, what ARM calls big.LITTLE. That's what the Exynos 5 Octa uses, a quad-core Cortex A15 is the big component and a quad-core Cortex A7 is the little. That way, you can switch back and forth depending on how heavily you are using the device, saving power when you're not using it much. ARM is pushing this in a big way and even though not many chips have it yet, if it becomes common, the Exynos 5 Dual will be behind. Of course, Android will still always support non-big.LITTLE chips, you just won't get the benefits of big.LITTLE. A little chip would have been particularly useful given the high power draw of the big chips in the Nexus 10.

Four or so updates is a lot for Android; I don't think you'll really find a phone other than a certain HTC phone (hint, it started with Windows Mobile) that'll get more than that. Keep in mind that even the lowly single-core Nexus S got its update to Jelly Bean-- I also have the Nexus 10 and HTC One, and both have the horsepower to stay in the game for quite some time. As a Galaxy Nexus user as well, I can also say that even relatively underpowered devices can stay kicking for some time.

Is there a better tablet or there than the N7? Right now. The screen resolution should be superior to all other tablets but next to an iPad with the same game playing this isn't as good. My girlfriend proved that. She likes i anything. I'm an android guy. Is the gpu not so good in this device? I like it don't get me wrong. But I just bought it and if there's ifs something better I would rather have the latest and greatest. I really do not understand why this isn't powered by a quad-core. I feel like my son's nexus 7 had better graphics. At least when I look at his screen it just looks better to my eye.

This dual core/quad core thing is a red herring, sorry. The Nexus 10 went with a dual core A15 because the performance boost provided by an A15 was such that Samsung could afford to use a dual core chipset (meaning reduced power consumption, both due to reduced core count and improved architecture) while still blowing out all comparable chipsets at time of launch. The Tegra 4s (if they're not hobbled by memory bandwith issues like the Tegra 3s) will be a half/full generation ahead of the Exynus 5250 when they launch, so you could sit and wait for those (they also have pretty good GPUs).
The Nexus 10 has a powerful GPU, but some of it gets sapped by driving the enormous screen resolution. As far as the screen goes, it's an amazing 10" IPS panel without too much else to say. The Nexus 7 has a WVGA 1280x800 IPS panel with significantly lower PPI, and you generally hold a 7" tablet a bit closer, which can compound the density drop. However, on a 7" device, it's hardly bad.
The Nexus 10 is going to beat the crap out of the Nexus 7, but if you want to switch, I'd wait for the next Nexus 7 (which is rumored to have an upgraded screen and proc in a similar price envelope as the original), or for the first Tegra 4s. There's not really much else on the market that'll beat a Nexus 10 right now in tablet-land.

Just a quick reply to point some things out. The Snapdragon 600 in the One is a quad-core A15 with Krait 300 architecture. The 600 is about as powerful as the 5250 with better multi-threading. Also most chipsets currently use A15. It is the current standard, not something that will "happen over time". The CPU has nothing to do with the screen res, the image processing is done through the GPU. And finally, I expect the 5250 to be eclipsed relatively soon, as chipsets supporting higher clock frequencies(like the 800, or even the rumored Tegra5/6 with a possible 3.0Ghz clock) start to enter manufacturing. Sorry for the brevity, I'll edit this a bit later when I get more time.

Tegra 5/6 is purely theoretical at this point. It's also best for clarity to note that most new chipsets are switching to A15 (or customized variants thereof). Most chipsets in the market right now are A9 or lower, and there are still phones being released running high-end A9 kit. The CPU also does have some role to play in screen drawing, especially for handling elements that are not using GPU rendering for one reason or another. This interaction isn't as significant as some would believe, but it cannot be discounted entirely either.
The Snapdragon 600 is probably on par with the Exynos 5250, that much is definitely true. They're pretty neck and neck and will outclass one another on different aspects of CPU performance, but both are quite good.

Plus the rumor is that Android 5.0 is being heavily optimized so it can run even on older phones, even with 512 MBs of RAM. If true, they may keep current devices updated for a while, as it may take a while for Android to bloat up again. :highfive:

lol @ the "up again." Hopefully they keep moving in this direction, towards leaner, sleeker software. And one of the nice kicks about modern, flat, industrial design is that it doesn't hit system resources quite as hard.

As Rirere says, Koopa777's post is pretty much all wrong. Krait is not Cortex A15, it is a unique design from Qualcomm that is somewhere between Cortex A9 and A15, which are off-the-shelf designs from ARM. Most current chipsets are Cortex A9, not A15. The Exynos 5250 Dual will of course be eclipsed with time, for example, the Tegra 4 will be coming out later this year with a quad-core Cortex A15, but right now the 5250 is basically the only Cortex A15 chip, other than the aforementioned Octa, which just came out.
As for Tegra 5/6, those won't come out till next year, I don't think anyone is planning on waiting till then.

Got to say, I'm looking forward to the next generation. I upgraded from a Galaxy Nexus (TI OMAP 4430) to the Snapdragon 600, and it was like night and day (the Nexus was my first smartphone, although I'd played around with many Android devices before). Amazing what processor tech is like these days.

Eh, if it's using twice as much power to get these results, who cares? Let's see how the battery life is.
I picked up a HTC One X+ with the fastest Tegra 3 and it gets very hot when playing 1080p video, burning battery like crazy. Even the Exynos 5 Dual in my Nexus 10 runs pretty hot when playing 1080p video. All these processors are powerful enough these days, whether they'll kill your battery or not is the real test.

Hot can be a sign of bad heat flow though, more than power consumption. A15s are better than A9s in some efficiency regards, but pumping them up to a higher clock speed will eat through that saving.

I have a Nexus 4, no Nexus 7. Have an iPad 3 but want something more portable so don't know if I should get the new N7 or wait for an iPad Mini update. Tied into both ecosystems, but if I go all Android, there's a lot of money wasted on iOS apps.
Also, how do you change names? My girlfriend set this up but doesn't use the account anymore - or is it best to just start a new account?
You can either use multi-user functionality or detach current Google account from tablet and set it up with a new one again.
Nexus 7 is also really portable. It fits into my back pocket and I'm going to everywhere with it without any hassle. iPad 3 in the other hand it's a gigantic device compared to Nexus 7 because it's bigger than 10" and also it has a 4:3 display makes it even more harder to carry around with ease.

You could try asking an admin, but your best bet would be to just create your own account.
I would say yes but this devicenis more capable. I know LG is known for thermal throttling on their mobile phone line. Those constraints won't apply to this new device. Its able to run hotter longer. So even if not stock, once Roms come out, this device/processor can be pushed alot more than in a phone.
Btw, I disabled thermal throttling. On my LG optimus G pro with Snapdragon 600 and Andreno 320. It runs great. So the S4 can be easily pushed past stock limits with no problem.
Eh, its smooth enough. Really no lag at all, but then again, I never had the 1st Nexus 7, so I don't know if that lagged at all. Overall, I couldn't care less whats inside as long as its smooth and fast for the user (me). The ipad mini has 1/4 the power of this, and it runs just as smooth.

I read something like this already, but I'm a bit skeptical about it. Why would Google advertise the lower spec than they actually are?
If this is true, than it's a gamechanger as krait 300 cores are some 30-40% faster than their older (krait200) brothers.

Yea we have an underclocked S4 600. So its faster then the N4. Also the memory bus has been increased.
The N72 is faster then the N4 but probably nothing noticeable right now. Perhaps with KLP, the additional memory bus and newer CPU instructions might distance the N72 further away from the N4, but who knows.

I would say the Snapdragon 800 because more devs would get it= more roms, better clock speed, better battery life because of chipset enhancements, faster charging because of chipset enhancements. If none of those matter to you get the Exynos version.

To be technical, it seems that Exynos benchmarks are slightly higher. However, I believe that is without the HMP update. With that, scores will skyrocket.
I can't make my mind up whether to get snapdragon 800 version or exynos 5420. By performance i mean which can do more multitasking and which can run apps faster etc
From what I've seen the scores are indeed about the same on the benchmark front. They will both be good! I'm guessing the s800 will get more dev support and probably cm. It will all be your choice, do you want lte or not.

One thing that pushes me towards the exynos is that it has 1866 ram speed whereas snapdragon only has 800
Which do you think will be better in the long run?
^^^ forgot to mention that because exynos has higher ram speed then that means quicker performance.
So, which one should I get? Will there really be any difference between the performance of exynos 5420 and snapdragon 800?
You really do seem to have an attitude in your posts. Anyways, the phone isn't out yet so all anybody has is benchmarks to go by. Not a lot of real world use reviews out there to compare the two.

I guess the ram speed can be neglected in real life usage. The s4 with the s600 feels the same as the octa version to me. And that is while the octa s4 obliterated the s600 in Antutu and some other Benchmarks. Like I've said before, if you want lte and better rom support get the s800 one. If you're really spec whoring get a 8 core exynos.
Anyways, from what I've seen so far the s800 seems to be faster in Antutu but not that much so I guess they will be at the same level of performance.
I would get any device I could get which for me is the s800 since I'm from the Netherlands.

Easy. Snapdragon since there will be much more support for it from developers.
Also, don't forget, the 8-core is a lie
You have your normal 4-cores with an additional 4 'smaller' cores to handle always running less intense things. I really don't see the advantage to this, you don't get more out of benchmarks because those 4 'smaller' cores won't be used, except by some obscure background task that wouldn't slow down the benchmark anyways. It also won't help with the battery life, no matter how you spin it a clock cycle is a clock cycle.
The only time you will see gains from small memory speed increases are in things like calculating pie, so again, useless for day-to-day stuff. As other have stated, support. Qualcomm based will get AOSP based roms without any problems.
If you are looking to flaunt your meaningless bigger numbers around, by all means, get the 8-core.

You have your normal 4-cores with an additional 4 'smaller' cores to handle always running less intense things. I really don't see the advantage to this, you don't get more out of benchmarks because those 4 'smaller' cores won't be used, except by some obscure background task that wouldn't slow down the benchmark anyways.

Not true anymore. They are releasing an update to run all 8 cores at the same time to make it a true octacore

I thought they were. Wasn't it something like a Heterogeneous or HMP update.

It can't be a true 8-core. The extra 4 cores are far less powerful then the other 4.

Let me tell you some preludes:
The reason behind using 8 cores was to put in a pair of four aggressively powerful quad processors like the cortex A15 with another pair of less powerful yet more power efficient four quad processors like cortex A7.
This is the main intention behind putting all these 8 cores of ARM's big.little architecture. The purpose is to let the A15s handle power hungry tasks like web page opening, playing an asphalt 8 game etc while the a7s would handle "simple" tasks. This is more vividly demoed in this video:
http://www.youtube.com/watch?v=Zwbeb08W27U
Now, the way you are saying it is not a true 8 core processor as if you are
1. demanding 8 cortex A15 processors using 28 nm technology.
Do you know/have any idea what could happen if they all be available online at the same time in this case?
or
2. you knew there was a "true" octa core processor in the world, to be (or already) implemented in another device. IF SO, point us to that device and also explain what is the ideal to call a processor true 8 core.
It was never an intention of ARM to put eight A15s (for example) available for heterogeneous multi-processing.
Go here. Again 64 bit A57s are to be paired with 32 bit A52s.
Even the S4 equipped with exynos 5410 is an octa core processor device. It is just that the bloody CCI (cache coherence interconnector, CCI400) was crippled to enable all the 8 cores available online. Once the 8 cores packed in a SoC like this it is an octa core processor device. Whether or not you like it to call true 8 core.
Samsung/ARM worked on this and released another SoC (in the form of upgraded exynos) which has a working CCI that is free from the above mentioned flaw(s) which will have Cluster Migration by default and will receive the update that is made from Linaro team to enable all the 8 cores available online and therefore will become a "TRULY WORKING" 8 core processor which is implemented in Note 3.
These are facts, these have been heavily discussed in the general section of Samsung Galaxy S4 forums.
Oh, another thing- just because all these 8 cores are made to be available online it does not mean all the 8 cores will be working Simultaneously regardless of what application is in the process. Depending on the needs of the app(s) all these 8 cores (ranging from 1 core to the extreme case- 8 cores) can be used. If an app needs 4 cores, they can be used. If it needs 6 cores then they can be used. If it needs 8 cores then they can be used.
I personally am curious to see how it be going when all the 8 cores were used for an app.
And to the OP who's demadning a straight answer, my thoughts:
we do not know anything atm how power efficient and cool it'd be to have the HMP doing all these tasks. This requires
real life buyers buy the device
start playing with it
see how hot the device becomes (compared to another exynos device like s4).
It actually depends on those stuffs. You demand the answer as if we all knew from the beginning how exynos 5420 gonna perform in real life.
